ABSTRACT:
.A mechanism and a method for converting a fixed wheeled walk-behind mower into a caster wheel walk-behind mower and vice versa comprising two caster wheel assemblies having wheels mounted in brackets journalled for rotation in frames. Each frame has means for attaching the mechanism to the front wheel axle. Each caster wheel assembly comprises an elongated member connected to each frame and extending the length of the mower on e.ach side between the frame and the respective rear wheel axle or mower housing. At the end of the elongated member most remote from its connection to each of the frames, a U-shaped notch is formed therein for connection with the housing. A tie rod is provided for interconnecting the two frames, for adding rigidity to the assembly and for maintaining the correct, constant distance between the frames. The mechanism can be rapidly converted between castering and a conventional walk-behind mower with fixed direction wheels with the only modification being the forming of a groove in the rear axle proximate each rear wheel.
